Questions:

- What year is your X? 2004 and above have angel eyes stock but not 2003 and below.
- Are you asking about LED angel eye replacement bulbs (2004 and higher) or are you wanting angel eye assemblies that you want to add to your headlights (2003 and below)?

I'm not familiar with the UHPs but those angel eyes in that link look like regular ebay AE replacement bulbs.

Search and you'll see plenty of info.

Here's my comparison of ebayers and AIBs v3.0:

I wish I had CCFL angel eyes, those would be awesome.
